Splunk for Palo Alto data collection

Hello,

I forwarded my palo alto logs to my splunk server. I can see all logs on the splunk server, but no in the palo alto APP. How much time the Splunk Palo Alto APP will display the results ? Because right now, and since this morning, all results are "0" or "Waiting for data"

Thank you for your answer. Best regards, Jamel
